SLB-30-100NM 30.0 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 400-700nm
This is a Plano-Concave Spherical Lens, type SLB-30-100NM, sourced from OptoSigma. The lens has a diameter of 30.0 mm and a focal length of -100.0 mm, making it a negatively powered lens. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens's geometry includes an edge thickness of 4.2 mm and a center thickness of 2.0 mm. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of -51.9 mm on the curved side. The back focal length is -101.3 mm.
This lens is coated with an Opt M coating on both the front and back surfaces. This coating enhances the lens's performance in the spectral range of 400-700 nm, making it suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
